STM32N6 Boot Pins

Hello, I have the STM32N6570-DK kit. I can compile, upload and debug by following the instructions on the kit. I designed my own board but I can't debug. I'm reviewing all the possibilities and I noticed some problems. I couldn't find any explanation.

@B.Montanari  's  article says H(High) VDDIO. However, in the DK schematics and pcb, the left side is vddio and the right side is gnd. Also, the Boot1 pin is pulled to the right to load software on the DK. So Boot0 becomes important. What's the problem? Are the documents wrong? Also, on the board I made, I can load software when boot1 is connected to vddio. But on the DK, it allows me to load software when boot1 is GND. What's the explanation?
